ELECTRICALLY ILLUMINATED TOOL DEVICE Application filed June 13,

This invention relates to electrically illuminated tool devices.

The particular application ofithe invention is concerned with theprovision of illuminating means for tools or instruments such as safetyrazors, or for use in conjunction with magnets, either of the permanenttype or those in which a solenoid is used to magnetize soft ironcore.The uses contemplated are such as where a magnet would be used fortheremoval of steel or iron splinters-from eye-balls, or for similarpurposes, inwhich the conjunction of the light directing source and thespecifictool or instrument to be used are essential.

. In a specific embodiment of the invention," as herein disclosed, theobject of the invention ,is to provide a casing of substantiallyone-plece construction within which casmg the battery for actuating thelighting means,

and in a desired case, the electro-magnet, is housed. ,An' integralportion extends from the casing and is designed to support any one ofa'plurality-of different types of tools; The support provided issubstantially rigid but does not in any manner, limit the removabilityof the tool and the replacement thereof with some other tool suitablefor. use in the combination related. y

A further object of the invention is to provide in conjunction withapparatus of the typeabove set forth, a means for simultaneouslyconnecting, incircuitwith an electrical energy source, housed Wll'llllilthe casing,

1 both the electrieiighting means and another electrically operated toolwhich may be mounted upon thecasing for co-operation with the electriclighting means.

Another object of the invention is to provide apparatus of the typehereinabove set forth which is simple in its construction, lendsitselfto economy and ease in manuface ture, andwhich requires littleskill in its use.

Other objects will be apparent from the specification, and the drawingsherein, which are madea part thereof, or will'be specifically pointedout therein.

The invention is not intendedto be restricted to the construction andarrangement of parts herein shownand described, nor to the 1930. SerialNo. 460,971.

Fig. 5 is a detailed assembly view of an electro-magnet designed for usein conjunction with the tool holders above set forth, but I moreespecially for use with the tool holder of Fig. 1.

In the specific embodiment of the invention disclosed in Fig. 1. thecombination electric lighting device and tool holder is seen to consistof a casing 12, a tool holding portionl l, an electric battery 16, a.combination base and switch member 18, an electric light bulbretainingmeans having an electric light bulb assembled therein, and any suitabletool for cooperation with the apparatus, such as the electro-magnet 22.l

The particular assembly and the relation of the parts therein are not tobe taken to be conclusive of the extent of the invention scriptionhereinafter, the construction might be varied without departing from thespirit of the invention. In the specific embodiment of theinvention ofFig. 1, the casing12 is preferably made from a piece of metallic tubing,the diameter of the bore of which is such as to receive snugly thereinthe electric battery 16 which may take the customary form of a batterymade up of a plurality of dry cells arranged in end to end relation,with the positive electrode of one in contact with the negativeelectrode of an adjacent cell.

The casing is preferably cut away at one end thereof so as to leaveremaining an integral extension 24 which may be shaped, in any desiredmanner, for ornamentation, and to assure the necessary rigidity for thetool holding portion 14 of which it forms a part. The end 26 of theextension may have a strip of the metal running circumferentially of thetube left intact therewith, which strip may then be bent to form an ear28, the internal diameter of which would be less than the diameter ofthe threadedportion of the tool which is to be connected ith the toolholder.

Preferably, the end of the strip would be anchored to the extendingportion in any well known manner, such as by soldering such end to theextending portion, after which the ear may be drilled and tapped for thepurpose of roviding a threaded receiving element with which the tool mayreadily be assembled, or from which it may readily be detached.

At the point of junction of the extension 24 with the body of thecasing, means, such as a socket 30, is seated within the bore of thetube and preferably takes the usual form of an electric light bulbreceiving and retaining socket with which an electric light bulb 32 ofany customary type may readily be assembled, or from which the bulb maybe separated at will. I

Preferably, the socket is slightly enlarged at the outer end thereofwhere is positioned the opening into which the bulb end is inserted formaking the necessary electrical connection. The tube at the point ofjunction thereof with the extension 24 is spun, or otherwise worked soas to provide a substantial ledge 34 upon which the enlarged end of thesocket may rest. In one embodiment of the invention, the socket may beforced down through the tube against the edge so that the naturalelasticity of the metal will cause it to bind against the walls of thetube and to make electrical contact. therewith. Further spinning of themetal at point of junction may be resorted to in order to insure perfectretention of the socket by the tube metal. However, if it is desired toinsure electrical connection between the socket and the tube walls. forpurposes hereinafter appearing, and also, simultaneously, to fix thesocket more firmly in position relative to the tube wall, soldering ofthe edge to the ledge may be resorted to.

In Fig. 2 is illustrated another form of the tool holding portion inwhich case the extension 36 may be formed integral with the body portion38 of the tube, in the same manner as above described. However, for thismodification, the extension is not bent away from the circumference ofthe tube, but is merely cut away to provide the pointed end 40 uponwhich may be seated any such means such as the machine screw 42, theslot 44 of which has been seated over the end 40 and secured integrallytherewith by means of soldering or the like. In this manner, there isprovided a screw with which may be assembled, in a well-known manner,such implements as a safety razor, screw-driver, and other similarimplements and instruments which might be associated for use inconjunction with the light directive means of the light bulb and thebattery therefor.

If desired, the construction of Fig. 1 may be formed with an extensionsuch as shown at 36, and aninternally threaded bushing or similar meansis secured to the extension by soldering or the like.

In the modification of Fig. 3, the tube wall is seen to have been cutaway in such manner as to leave extending therefrom two portions 46 and48, disposedsubstantially diametrically opposite each other. The ends ofthe portions are bent inwardly toward each other so that semi-circularcut outs in the ends of each of the portions may be brought into matingrelation to form an opening. A threaded pin 50 is then positionedthrough this opening, the head of the pin providing a stop to positionthe same relative to the portions 46 and 48. Preferably, the opposedends of the portions are brazed or otherwise united firmly to each otherand the pin 50 is soldered or otherwise firmly and securely assembledwith the brazed ends of the portions.

In the modification disclosed inFig. 4, the extension 52 has assembledtherewith in any suitable manner two bushings 54 and 56, the openingsthrough which are aligned and are preferably unthreaded. The opening ofthe outer bushing 54 is suiiiciently large to receive therethrough theenlarged projection 58 of the spring member 60, the end 62 of the memberbeing adapted to seat in the bushing 56. Pressure is applied to thespring member until the enlarged projection may be slipped through theopening of the outer bushing. The spring member is then pushed throughthe bushing until the end 62 seats in bushing 56 and the projection 58,when the projection has passed beyond bushing 54 and pressure isreleased from the member, rests snugly between the bushings to retainthe member anchored in position relative to the extension. 'One end 64of the spring member may be formed to receive thereon a suitable toolsuch as a mirror for use in dentistry, or the like. Such tools are thusmade capable of ready and immediate assembly with and disassociationfrom the support.

In one preferred embodiment of the invention, as shown in Figs. 1 and 5,an electromagnet is assembled with the apparatus in such fashion thatthe solenoid of the electromagnet derives its power from the same energysource as the electric light bulb, that is, the dry cell batteryhousedin the casing. In the. construction herein, the electro-magnct22may be assembled upon the ear'28 in the same manner as an electric lightbulb is assembled with itssocket, so that a conductor may be led awayfrom thescrew mounting to the electro magnet, which is thus electricallyconnected with the casing wall. A spring fin- 1ger 66 may be assembledon the extension and e insulated therefrom so that the end of theelectro-magnet, which has an insulated electrode 67 extending therefrom,may be brought into contact with the finger which is electricallyconnected with an insulated electrical is preferably seated in a disc 71offibre or similar insulating material and may be posiing of the bushingtioned on the end of the battery soas to make electrical contact withthe electrode exposedat that end.

- In this relation it is to be noted that it is desired that the carbonelectrode be positioned adjacent the electric light bulb and the bushing70 so that the latter may en circle the electrode, asshown, and permitthe end of the electric light bulb to make electrical-contact with theextending end of the electrode in the usual manner. The introduction ofthe bushing 7 O, in this manner, eliminates interference with theassembly of the electric light bulb. For this purpose, therefore, theconductor 68 is secured to the body of the socket and ofthe tube in suchmanner as to support the bushing transversely of the tube and toposition the open.-

70 centrally of the tube. Preferably the bushing and the disc retainingthe same are of slightly smaller diameter than the tube proper so thatthe disc will be retained centrally of the tube.

The end 74 of the tube is internally screws threaded to associatetherewith the screwthreaded flange76 of the base 18. Extending from thebase are a pair of pins 78, extending through openings in an insulatingdisc 80.

e A spring 82 between-{the disc and the base i is rotated in apredetermined direction, the

serves to retain the battery pressed against the contact of the lightbulb. WVhen the base pins 78 Will. be moved transversely through thedisc and make and break contactwith the bottom surface of the battery,which constitutes the other electrode thereof, thereby making andbreaking the circuit of the bat tery and the light. Since the base isreceived snugly and in metallic and electrical contact with the walls ofthe tube, the contacting of the electrode and the pins pro- :vide's asimple switching mechanism forthe operation ofthe electrically energizedmeans associated with the device. e As..many changes could be made inthe construction herein involved, and many widely different embodimentsof the invention designed without departing from the scope oftheinvention, as defined in the accompany ing claims, the matter setforth by the above description may be interpreted as illustrativev ofoperative embodiments of the invention and not in alimiting sense.
